Using the map size walk through walls or its related exploit (map size memory corruption), it is possible to glitch the current position on the Start menu. Pressing down may bring the cursor back to the top of the menu (Pokédex), where the player can continue to proceed to the party (or items, although the player may already have the expanded item pack at this point).

Upon opening the party, the cursor will be beyond the normal limits based on how many Pokémon the player has (normally 1-6). For the Red/Blue Vermilion City method, this may be at party Pokémon 235.
